Leak-tightness test on deck for SRS mega unit
The Savannah River Site in South Carolina will begin a leak-tightness test to qualify the megavolume Saltstone Disposal Unit (SDU) 10 to store up to 33 million gallons of solidified, decontaminated salt solution produced at the site.

This paper describes evaluation results of thermophysical properties of stainless steel (SS) containing 5 mass % boron carbide (B4C) in its solid phase. First, the authors synthesized SS-B4C samples with emphasis on 5 mass % B4C and SS using a hot press method and then evaluated its homogeneity in several ways, such as chemical composition analysis, metallographic structure observation, and micro X-ray diffraction. This study also evaluated the density and the specific heat and thermal conductivity of the SS-B4C sample and found that the density becomes lower and the temperature dependence of the density decreased as the temperature rose compared to that of stainless steel Type 316L (SS316L) used as a reactor material. The specific heat became slightly higher than that of SS316L and showed similar temperature dependence up to 1073 K. Unexpectedly, the thermal conductivity became lower than that of SS316L and showed similar temperature dependence up to 1273 K.
